TOP ROLL FOR SPINNING-MACHINES, 86C.

SPECIFICATION forming part of Letters Patent No. 320.333, dated June 16,1885.

(N0 model.)

To aZZ whom it may concern.-

Be it known that we, WILLIAM T. CARROLL, EDGAR J. CARROLL, and ELBERT H.CARROLL, citizens of the United States, and residing atlVorcester, inthe county of Vorcester and State of Massachusetts, have inventedcertain new and useful Improvements in Top Rolls for Spinning-Machines,&c.; and we do hereby declare that the following is a full, clear, andexact description of the invention, which will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of thisspecification, and in which Figure 1 is a vertical sectional view of ourimproved roller for drawing-frames. Fig. 2 is a perspective View of thesame,showing one of the shells removed and shown beside the shaft. Fig.3is a view of one ofthe hollow oil-conducting bearing-pins. Fig. 4 is aview of one of the anti-friction shells. Fig. 5 is a perspec tive viewof a slight modification of the invention,showing oneshell removed fromthe shaft; and Fig. 6 is a longitudinal section of one end of the same.

Similar letters of reference indicate corre sponding parts in all thefigures.

Our invention has relation to the weighted leather covered rollers usedin a d rawingframe or similar machinery, together with fluted rollersfor drawing slivers; and it consists in the improved construction andcombination of parts of the shafts, bearings, and rollers, ashereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the shaft, the endsof which are hollow, as shown at B, for the reception of the reducedinner ends, C, of the bearing-pins D, which have square or flattenedheads E,which are secured in the support for the rollers movablevertically in any suitable manner, and a duct or channel, F, opening inthe inner end of the pin and in the upwardly-tacing side of the headadapted to conduct Oil or similar lubricant into the hollow ends of theshaft. The middle portion,G,of the shaft is adapted to revolve in asuitable bearingin the weighted or spring-actuated saddle,which holdsthe roller down against the fluted rollers, and the ends H of the shaftare reduced and have wide annular recesses I, in which anti-frictionshells or tubes J are placed, turning freely upon the reduced portion ofthe shaft and being flush with the shoulders at the ends of the recessesat their ends, and increasing in thickness toward their middlcs, so asto offer a curved surface. The shaft has perforations K at its ends,passing from the hollow chambers formed in the said ends and opening inthe annular recesses upon the ends of the shaft, and the anti-frictiontubes or shells have perforations L, registering with the perforationsin the shaft, thus allowing the lubricant to flow from the interior ofthe ends of the shaft between the annularly-recessed portions ofthe'shaft and the anti-friction shells and over the latter. The tubularshells M, which have preferably a leather-covering, M, are journaledupon the ends of the shaft, turning upon the anti-frie tion shells; andit will be seen that the antifriction shells, being thicker at theirniiddles than at their ends, the leather-covered shells willbe enabledto adapt themselves to any inequalities of the stock passing under themand to find themselves a bearing.

In Fig. 5 is shown a slight modification of the shaft-,which dispenseswith the annularlyrecessed ends and anti-friction shells, and has itsends reduced and formed slightly bulging toward the middle, and providedwith spiral channels N, which serve to conduct the lubricant from theperforations in-the shaft,through which it passes out over the entiresurface of the reduced end. The bearing-pins are also shown providedwith screw threaded ends, which fit into the femalethrcaded ends of therecesses in the ends of the shaft, thus rendering the shaft rigid whilethe shells revolve.

Having thus described our invention, we claim and desire to secure byLetters Patent of the United States- 1. The combination of a shaft,having its ends provided with recesses or bores and with perforationsopening from the said bores in the sides of the shaft, bearing-pinshaving their ends fittingin the bores of the shaft, provided with anenlarged flattened head and IOO with a channel opening in the upper sideof the said head and in the end of the pin, and

a shell or tubular roller jonrnaled upon theend of the shaft, as and forthe purpose shown and set forth.

2. The combination ofthcshafthaving the red need ends provided with theannular recesses, the anti-friction shells fitting and turning in thesaid recesses and having their middles thicker than their ends, and theshells or tubular rollers, as and for the purpose shown and set forth.

3. The combination of the shaft, having its ends provided withlongitudinal bores having openings through the sides of the ends andhaving the Wide annular recesses, the antifriction shells increasing inthickness at their i-nesses:
